Technical Field

[0001] The utility model relates to the technical field of sandstone aggregate production, in particular to a lubricating device for sand making machine parts. Background Art

[0002] The vertical shaft impact crusher is the key equipment of our company's sand making production line. The main shaft is one of the important components of the vertical shaft sand making machine. Its function is to transmit torque and drive the rotor of the vertical shaft sand making machine to rotate at high speed. When the main shaft runs at high speed, it will generate heat and vibration, which will have a significant impact on the service life of the main shaft. The lubrication and sealing structure used for the main shaft in the existing technology can easily cause the main shaft to lack lubricating oil, resulting in rapid heating and locking of the main shaft, and the need for manual shutdown to add lubricating oil. Utility Model Content

[0003] The problem solved by the utility model is to provide a lubricating device for sand making machine parts, which solves the technical problem that the lubricating sealing structure used for the main shaft in the prior art easily causes the main shaft to lack lubricating oil, resulting in rapid heating and locking of the main shaft, and the need for manual shutdown to add lubricating oil.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A lubricating device for sand making machine parts includes an oil storage cylinder, a cylinder cover, a metering oil pump, a first oil pipe, a diverter valve, a second oil pipe and an oiling nozzle, wherein the cylinder cover is detachably mounted on the oil storage cylinder, a metering oil pump is mounted on the bottom side of the oil storage cylinder, the metering oil pump is connected to the diverter valve through a first oil pipe, the diverter valve is mounted with two oiling nozzles through two second oil pipes, and the two oiling nozzles are respectively mounted on the top and bottom of a main shaft lubrication sealing structure.

[0006] Preferably, the oil storage cylinder and the cylinder cover are connected by threads.

[0007] Preferably, a stirring shaft is rotatably mounted in the middle of the bottom side of the cylinder cover, and a plurality of stirring blades are mounted on the stirring shaft.

[0008] Preferably, a motor is installed on the top side of the barrel cover, and the output end of the motor is connected to the stirring shaft.

[0009] Preferably, an electric ring seat is installed on the outer side of the oil storage cylinder, and a wire is electrically connected to the electric ring seat.

[0010] Preferably, a plurality of resistance heating wires are installed inside the electric ring seat and inside the oil storage cylinder.

[0011] The beneficial effects of the utility model are as follows: the device is started synchronously with the sand making machine, and the lubricating oil is automatically delivered to the lubricating sealing structure of the main shaft through the work of the quantitative oil pump, thereby ensuring the normal use of the main shaft and extending the service life of the main shaft;

[0012] The motor drives the stirring shaft and stirring blades to stir regularly to avoid the precipitation of the lubricating oil. When used in a low temperature environment, the electric ring seat located on the outer wall of the oil storage cylinder heats the internal lubricating oil through the resistance heating wire when the wire is energized to avoid the solidification of the resistance heating wire, which makes it impossible to add the lubricating oil in time.
